"Imagination is more important than knowledge." (Albert Einstein)
Rather than learning everything from given facts or knowledge that’s already been provided, using imagination will get you further in developing knowledge. Also, having a lot of knowledge, but not being able to apply imagination to make that knowledge more creative and useful doesn’t get you anywhere. Don’t let knowledge takeover your brain, and make room for creativity.

"If you would keep your secret from an enemy, tell it not to a friend." (Benjamin Franklin)
Keep the secret instead of telling it even to a friend. It’s not longer a secret if another person knows about it, and why not just keep the secret from a friend when you can keep it from an enemy? Secret is best kept when only one person knows it, and it’s also guaranteed to be more safe. Importantly, once you decide to keep it a secret, keep it, and never share it with anyone else. Sharing may bring disaster or problems.

"The smaller the heart, the bigger the hate it shelters." (Victor Hugo)
Having small room to store kindness will increase more hate and the hate will be stored in the place of kindness. Learning to spare kindness is important and having a bigger heart will result in more goodness and benefits may be gained.
